The IQ Panel 4 / IQ Panel 5 can support the System Sensor COSMOD2W and the System Sensor
COSMO-2W smoke/co detectors by using the IQ Hardwired PowerG module, a HSM2300power supply and a HSM2108 zone expander. Smoke and CO zone wiring needs to be separated between the main module and a zone expander.
The COSMO2W loop is monitored by the system for three states of the detector’s circuit
through the fire zone connection to the COSMOD2W (SMK IDC +, SMK IDC -).
- 3.9k resistance is a Normal state on the loop. 5.6k is presented to the zone.
- Reduction of resistance toward 0k is an Alarm state. (Detector alarm or short)
- Increase of resistance toward ∞ is a Trouble state. (Loose or broken wire)
COSMOD2W Wiring:
COSMOD2W Setup
The output from PGM1 in this setup is programmed as a ‘Siren Follower’ trigger (pulsed
or steady output based on alarm condition), Dip Switch #1 MUST be set to ‘ON’.
HSM2300 Power Supply Wiring
The PG9WSLHW8 / PG9HRDW8 is limited to 110mA standby current draw for the
Corbus, Aux1+ and Aux2+ when meeting an UL Residential Fire and CO listing.
The HSM2300 is limited to 250mA standby current draw when meeting an UL Residential Fire and CO listing.
HSM2108 Zone Expander Wiring
The Fire zone and the CO zone from the COSMOD cannot be wired into zones on the same module – they MUST be split between the main module zones and the zone expander zones.
- If the Fire zone and CO zone from the COSMOD are connected to
the same module, the IQ4 will ignore Life Safety zone fault troubles. - If the panel is not acknowledging the Life Safety zone fault troubles,
correct the zone setup and panel programming, then reboot the IQ4
panel.
Panel Programming
Program the zone for the COSMOD’s SMK IDC as ‘26-Smoke-Heat’ on the PG9HRDW8:
Program the zone for the COSMOD’s CO IDC output as ‘34-CO’ on the zone expander:
Program PGM1 as a ‘Siren Follower’:
Program PGM2 as a ‘Sensor Reset’:
Additional Notes
-
When using a POS+ trigger from the PGM programmed as a ‘Siren Follower’, any alarm that trips the bell output will sound with the siren’s cadence through the smoke detector sounders (e.g., Fire Alarm – Temporal 3, CO Alarm – Temporal 4, Flood Alarm – 1 second pulse, Burg Alarm – Steady, etc.)
- The annunciation patterns of the sounders will follow the priority assignment of the alarm condition. Higher priority alarms will override the annunciation of the lower priority alarms as needed: Fire, CO, Burg, then all other.
-
When using a POS+ trigger that follows the ‘Siren Follower’ PGM output, the CO Trigger wiring is optional. The COSMOD will automatically follow the bell trigger from the SMK Trigger as mentioned above.
-
When a detector is removed from its base, or the IDC detector loop is disconnected/interrupted from the COSMOD a Wire Fault trouble (Wire Fault LED = solid) will occur on the COSMOD, this will cause a Fire Trouble on the assigned fire zone. Once the detector loop is properly restored, the COSMOD’s Wire Fault trouble should clear in approximately 60 seconds, at which point the zone fault trouble on the assigned fire zone will clear.
-
When using the COSMOD with the PG9WLSHW8 / PG9HRDW8 module the COSMOD might trigger a momentary zone fault trouble on the assigned Fire and CO zones of the COSMOD when the fire alarm is reset.
- With the proper setup and wiring of the COSMOD, there is no way to avoid these momentary zone faults on the assigned zones.
