How do I set up the 5158 Zone Omit Unit

5158 Zone Omit Unit

The most common set-up on The 5158 Zone Omit Unit is as follows: -

1 From the 'To Panel' side of the 5158 Zone Omit Unit you will wire back to your control panel.

Note : If the panel uses ID biscuits or Resistors*, terminate them in the zone omit module and NOT in the device itself, i.e. Dual Tec. (* The resistors may be shown the wrong way round in the manual, the 4k7 should be parallel with the “ALM” and 2k2 should be in series with the “TMP”)

2 On the 'To Detectors' side of the 5158 Zone Omit Unit wire one of your two detectors to either 'ALM A' & 'TMP A' or 'ALM B' & 'TAM B' or link out the alarm and tamper(s) that you are not using.

3 Put the big multi pin “Mode” jumper on to 'Mode 2'. (This is on the left hand side of the 5158 Zone Omit Unit). This will allow the two zones 'ALM A' & 'ALM B' to be shunted, the tampers will not be isolatable. If left on 'Mode 1' only 'ALM A' & 'TMP A' will be operational.

4 Adjust the LK1 'Alarm latch' link to the unlinked position (Just right of centre of the 5158 Zone Omit Unit).

5 Position the 'FLT / ISOL SOUNDER' jumper on the 'FLT' side. (This is located to the bottom right of the 5158 Zone Omit Unit pcb).


5158 Unit Lid Tamper

The 5158 unit lid tamper spring is located at the bottom left of the PCB (NOT THE MICRO SWITCH IN THE CENTRE), a tamper on the 5158 Zone Omit Unit will be reported as a tamper for zone A (TMP A) of the unit. The unit will have to be powered up in order for the tamper to be seen as closed. The cover tamper micro switch is located at the bottom right of pcb. Note: the Micro switch in the centre of the unit is for the On Board Keyswitch for omitting the zomes, only utilised on the 5158S.2

Remote Keyswitch

If a remote keyswitch is to be used, it should be connected across 'KSW' and '0V'. The loop needs to be closed circuit to isolate the zone(s). You may need to gently bend the arm away from the 'SW1' micro-switch (this is the switch in the centre of the unit, if you have and onboard keyswitch leave it in the 'On' position.

Remote Isolate LED ('Isol' LED)

If you wish to install a Remote Isolatation LED, will need to connect the LED across from 'Isol LED' to '12v', you do not require a resistor. The LED will illuminate when the zone(s) are isolated.

Remote Fault LED 1 & 2 (LED1 & LED2)

If you want to have a Remote Fault LED, wire your LED from 'LED1' (or 'LED2') to 'COM' (No resistor is required).

If the Onboard Switch is returned to the 'On' position (or the Remote Keyswitch returned to open circuit) with the detectors still active or open circuit, Fault LED1 (or LED2) will illuminate depending on which zone is active.

5158 Operation

Assuming that all of the above set up has been used the 5158 will operate as follows: -

With the Onboard Switch in the 'On' position

Or the Remote Keyswitch open circuit: -

The state of the device will be reported to the main control panel as normal.

With the Onboard Switch in the 'Off' position

Or the Remote Keyswitch closed circuit: -

The ISOL LED will come on when the zones are isolated. (Led 3 bottom left-hand of the PCB) The 5158 Zone Omit Unit will isolate the zone(s) and the state of the device will not be reported to the main control panel.

If the Onboard Switch is returned to the 'On' position (or the Remote Keyswitch returned to open circuit) with the detectors still active or open circuit the unit will respond as follows: -

The 'Fault ALM A' (or B) LED(s) will illuminate, the fault buzzer will sound and the zone(s) will not be reinstated back to the main alarm system.

1 Turn the onboard switch to the 'Off' position (or the remote keyswitch back to closed circuit).

2 Make sure the devices are closed circuit (not active) then reinstate the zones by turning the onboard switch to the 'On' position (or the remote keyswitch to open circuit).

Circuit Isolated Relay

Should you require you can connect a transistorised relay, drawing no more than 25mA. As an example to signal into an Alarm control panel that zones are isolated: -

Connections: 5158   Relay
       
  12v to 12v
  0v to 0v
  Isol LED to 0v trigger
