Fire-Lite Alarms MS-4012 Instruction Manual page 15

Zone Relay Module (40xxZR) - One Form-C dry alarm contact per zone, one Form-A general alarm contact,
one Form-C trouble contact are provided with this option. The module is supervised for insertion (once jumper
JP3 on the main board is cut). If the 40xxZR is then removed, all four zone trouble LEDs and the system trouble
LED will come on, and the panel's audible trouble device sounds. Contacts are rated for 2.0 amps at 30 VDC
and 0.5 amps at 120 VAC. For applications requiring ULC listing, these contacts shall be derated to 2.0 amps
at 30 VDC and 0.5 amps at 30 VAC.
To install, remove jumper JP3 on the main board (Zone Alarm relays will NOT operate with JP3 installed). Plug
the module into connector P3 on the main board. Note that either this module or the LED Interface Board
(40xxLI) can be plugged into P3, but not both. Screw terminal connections are provided with each contact (see
Figure 3H).
The Zone Disable and Trouble Silence switches will not affect operation of the relays on the 40xxZR
module.
Note 1: Pin 2 is a Form-B general alarm contact. This pin provides a Normally Closed contact that will open only when ALL four
zones are in alarm.
Note 2: Zone 4 alarm contacts WILL operate if Zone 4 is programmed as a supervisory zone.
