9 SECTON 1 SYSTEM OVERVEW NTRODUCTON The Simpex 4020 is a microprocessor-based Fire Aarm System. t is UL-isted, power-imited, eectricaysupervised, and protected against oss of primary AC power and brown-out conditions. The standard 4020 can contro up to 127 points. Depending on options, the 4020 can contro a maximum of 254 addressabe points. Since a points in a system may not be addressabe, the 4020 aso offers up to 20 hardwired points (with 4 points standard) that can be used to interface with detector zones, be or horn circuits, and auxiiary reay contro. Each hardwired point is individuay configurabe as either a monitor point, a signa circuit, or as an auxiiary reay output, with up to 8 different points on a singe card. The 4020 offers a variety of ways to provide remote annunciation. t can communicate with the LCD annunciator, the SCWRCU, or the graphic SCWRCU. The RS-232 interface can be used to output to a printer or CRT. An aphanumeric dispay on the 4020 Operator nterface Pane (Figure 1) indicates the condition of the system. The aphanumeric dispay shows various prompts and abes which guide the user through a sequenced operation for each abnorma condition. Audibe and visua indications are provided to indicate abnorma conditions when they exist within the system. The 4020 capacities are as foows: Up to two channes with up to 127 addressabe devices each for a tota of 254 addressabe devices Up to 20 hardwired points, configurabe as monitor, signa, or auxiiary reay points An RS-232 interface Up to 31 remote annunciator ocations, which can accommodate SCWRCU, graphic SCU/RCU, and LCD annunciators An 8-Amp switching power suppy, with a battery charger capabe of charging batteries with up to 50 Ah capacity. The defaut hardware for a 4020 incudes a master controer with a dispay, master troube points, city circuit, and tone-aert. The standard save modue uses three card addresses. Card (address) 1 W functions ike an 8-point mutifunction /O card, but ony the first 4 points are avaiabe. Card 2 is the power suppy card. Card 3 is the buit-in MAPNET@ channe. The foowing optiona hardware is aowed: An additiona card Two eight-point mutifunctiona /O cards An RS-232 interface card configured with two isoated ports, with the abiity for one port to be dedicated to communications with a 2120 Mutipex System.

20 ESSENTAL ALARM CONDTON KEYS The essentia keys for aarm conditions are the <ALARM ACK> (Aarm Acknowedge), <ALARM SLENCE>, and the <SYSTEM RESET> keys. The remaining keys are conceaed by the interface pane access door and are associated with advanced system functions. (See Section 8, Advanced Functions.) ALARM ACKNOWLEDGE KEYS The <ALARM ACK> keys are ocated directy under the FRE ALARM LED and the PRORTY 2 ALARM LED. Pressing the <ALARM ACK> key (twice for ndividua Acknowedge or once for Goba Acknowedge) causes the ALARM LED to change from fashing to steady ON and siences the tone-aert. Pressing the <ALARM ACK> key does the foowing: Seects the next unacknowedged aarm point in the ist for dispay (ndividua Acknowedge) Acknowedges the dispayed point or acknowedges a points on the ist (Goba Acknowedge) Scros the points chronoogicay after a points have been acknowedged. f the <ALARM ACK> key is passcode protected, you cannot use this key to acknowedge aarms uness you have the required access eve. (See Operator Access Leves, Section 8, and Log n Procedure, Section 1.) There are two types of acknowedges for the 4020 system: Goba Acknowedge and ndividua Acknowedge. Each acknowedge type operates with the System Aarm Condition in the foowing manner. Goba Acknowedge - When Goba Acknowedge is used on the 4020 system, a singe key press of the <ALARM ACK> key acknowedges a aarm status changes in the system. f status change information is required, you may review this data by pressing the <ALARM ACK> key and reading the aphanumeric dispay. ndividua Acknowedge (For NFPA 72 Proprietary Receiver Requirements) - f an aarm condition has been acknowedged with the <ALARM ACK> key and further unacknowedged conditions remain in the system, the tone-aert continues sounding and the next status change shows on the aphanumeric dispay. This process repeats unti a changes are acknowedged. When this occurs, the tone-aert siences, and the highest priority acknowedge change appears on the dispay. ALARM SLENCE KEY CAUTON PRESSNG THE ALARM SLENCE KEY CAUSES FRE ALARM EVACUATON SGNALS TO TURN OFF: FOLLOW LOCAL PROCEDURES TO SLENCE ALARM EVACUATON SGNALS. When an aarm condition exists, various signas, auxiiary reays, the city connection, and the tone-aert may activate (depending on the type of aarm condition, the system configuration, and the stage of the aarm condition). The <ALARM SLENCE> key, when pressed, turns OFF a circuits programmed to foow the Aarm Sience key. The <ALARM SLENCE> key press wi: Turn OFF signa circuits Turn ON the ALARM SLENCED LED Dispay a message, such as the one shown beow. ALARM SLENCE N PROGRESS... 12

21 Aarm Sience Software Considerations The foowing software functions affect ALARM SLENCE operation. f a Coded nput Device is activated, the <ALARM SLENCE> key press may be ignored unti this function has competed coding. Notification appiances cannot be sienced when a coded station is in aarm. However, the fashing LED wi change from fashing ON to steady ON when the <ALARM ACK> key is pushed. The notification appiances sience automaticay upon coding competion. f the Aarm Sience nhibit Function is activated but not competed, the <ALARM SLENCE> key press is ignored. The message, ALARM SLENCE NHBTED, dispays for a short time to indicate the action was not taken. The message ALARM SLENCE NO LONGER NHBTED dispays when the inhibit function times out. f seected, the aarm sience inhibit may be programmed from 1 to 99 minutes. When seected, signas cannot be sienced unti the programmed time has eapsed. f Waterfow/Sprinker Devices are activated, notification appiances may or may not be sienced (depending on oca code requirements). Usuay, a dedicated be wi continue to sound to indicate water fow. Some visua notification appiances may continue to fash unti the system is reset. SYSTEM RESET KEY The <SYSTEM RESET> key is used to return the system to its norma state after a Fire Aarm Condition has been ceared. When the <SYSTEM RESET> key is pushed, it causes any atched circuits to reset automaticay. Aso reset are initiating devices, reays (incuding the city reay), notification appiances, and a LEDs and indicators which are programmed to reset with the <SYSTEM RESET> key. The message, SYSTEM RESET N PROGRESS, dispays when the <SYSTEM RESET> key is pressed. When the Fire Aarm Condition has reset, the FRE ALARM LED fashes, and the system requires that the <ALARM ACK> key be pressed. When the <ALARM ACK> key is pressed, a message shoud be dispayed that is simiar to the one shown beow. SYSTEM S NORMAL 8:37:13 MON 04-APR-94 f a zone stays in aarm during the reset period, the message SYSTEM RESET N PROGRESS message shown beow. is foowed by the ALARM PRESENT, SYSTEM RESET ABORTED When the SYSTEM RESET ABORTED message dispays, the system remains in an aarm state. The dispay indicates the tota number of aarms present in the system aong with a prompt to use the <ALARM ACK> key to review the points. These points do not require acknowedgment. The ALARM LED remains ON to indicate that a device is sti in an aarm condition. f the system does not reset, and the dispay sti shows an aarm athough no aarm condition exists, read the aphanumeric dispay on the interface pane to determine the type of device and the ocation of the device in aarm. Foow oca procedures to investigate the area of the buiding with the aarm. Look for devices sti in aarm (pu stations, smoke detectors, etc.). Most devices atch unti they are reset, either by the system or manuay. F THE ALARM PONT DOES NOT RESET f a device does not reset, you may choose to perform the Disabe Procedure given in the foowing paragraphs. 13

(See Section 9, How To Enabe A Disabed Point.) TROUBLE NDCATONS FOR TrueAarm SENSORS NTRODUCTON The devices that are used for the TrueAarm operation are considered sensors instead of detectors, because these devices do not determine aarm conditions. The TrueAarmTM smoke sensor is a measuring device that sends data regarding smoke density to the 4020 contro pane. The TrueAarmTM heat sensor operates in a simiar fashion, but sends temperature data instead of smoke density data. The 4020 uses this data to determine whether a troube has occurred. This basic operationa difference is the key to TrueAarm operation. The TrueAarm sensor has two automatic troube indications: Dirty, and. Excessivey Dirty. A Smoke Detector Dirty troube condition is reported any time the average vaue on an individua sensor reaches a set threshod vaue. At this time, the 4020 is sti compensating for environmenta factors and is hoding the set sensitivity eve. A Smoke Detector Excessivey Dirty troube condition is reported anytime the average vaue of an individua sensor reaches a higher than threshod eve. At this point, the 4020 can no onger compensate for environmenta factors, and the sensitivity eve wi begin to drift. Athough an excessivey dirty troube is reported, the sensor wi continue to operate and wi report an aarm condition if one is detected. n addition to the two automatic troube conditions, the 4020 software incudes a pre-programmed digita pseudo point (P132, Sensor Amost Dirty Log Enabe) that can be turned ON at the front pane to aow a TrueAarm sensor that is within 10 anaog units of being a dirty sensor to report as if it were one. This is usefu when maintenance is being schedued for dirty sensors, as it provides a means of seeing if other sensors are approaching a dirty state. 19

28 Once a minute, the 4020 software performs a sef-aarm test of each TrueAarm sensor. The sef-aarm test raises the vaue of each sensor to a vaue that simuates an aarm condition. f the sensor reports back a vaue that is not within the aarm range, a sef-test abnorma troube wi be dispayed for that specific sensor. The foowing paragraphs discuss the responsibiities of 4020 system operators when these troube indications occur. ALMOST DRTY NDCATON Using the front pane keypads, it is possibe for a SMPLEX Fied Service representative to turn on a system point that aows an amost dirty sensor to report a troube. Athough the amost dirty sensor is hoding its sensitivity eve, the 4020 operator can schedue maintenance for the sensor before the dirty sensor troube occurs. DRTY NDCATON A Dirty indication means that the sensor is hoding its sensitivity eve, but that the 4020 operator shoud schedue maintenance for the sensor. Cean the sensor as required and, if necessary, ca Simpex for service. EXCESSWEL Y DRTY NDCATON The Excessivey Dirty indication means that the sensor is no onger compensating for dirt and dust. Because fase aarms are possibe with this condition, sensors must be ceaned as soon as possibe. f necessary, ca Simpex for service. SELF-TEST ABNORMAL NDCATON A 4020 system sensors are automaticay tested once every minute. f a sensor fais to report propery to the 4020 master controer, a sef-test abnorma condition occurs. Since the sensor is not working propery, it must be repaced. Repace it, or ca Simpex for service. 20
