INSTALLATION AND WIRING:
Do not connect the battery or plug-in transform& tintil all other wiiirig has been completed.
Use of twisted wiring is recommended for all runs, for greater immunity to unwanted induced voltages.
Terminals: (See Diagram 6)

Description
Burglary Protection Zones: For each tone, run a pair of wires from that zone's
terminals to all protection points in the zone and terminate with a 1000 ohm End-of-
Line Resistor (supplied). Each loop has normal response to closed circuit devices
(such as magnetic contacts, foil, etc.) connected in series. In the Perimeter Zone,
for fast response to quick acting devices (such as vibration contacts and photo-
electric units without built-in delays), cut the YELLOW jumper wire on the unit's
chassis (Interior Zone: Cut the RED wire for fast response).
_
Note: If fast response is selected, the loop should not contain devices with
exposed metallic contacts (to lessen the chance of false alarms).
An open or short in the Interior or Perimeter loop will cause an immediate alarm
when the system is ON.
Devices with 0per-1 circuit contacts (such as mats) may be connected between the
wires of either loop. (Do not use an Ademco No. 602 Mat Coupler).
Maximum permissible resistance in each loop: 300 ohms (plus the 1000 ohm End-
of-Line Resistor).
Burglary Protection Zone: For this zone, run a pair of wires from the zone's ter-
minals to all protection points in the zone. The loop has normal response to
closed circuit devices connected in series. An open in the loop Hiill cause an alarm
after the'entry delay period has expired, unless the entry delay has been turned
OFF via the ENTRY DELAY (INSTANT) switch.
Fire Protection Zone:
Run the supervised fire detection loop from these terminals to all U.L. Listed
thermostats, smoke detectors, combustion detectors or other fire detedtion
devices to be used. Runs up to 500 feet may be made with #22 wire. Run one con-
tinuous loop (no branches) through all devices, connecting any trouble relay con-
'tacts in series with the loop and normally open alarm contacts across the loop's
two wires. At the last device, terminate the loop with the 1000 ohm end-of-line
resistor (furnished) and a No. 633 Supervisory Module.
Note: Low current smoke and/or combustion detectors such as the Nos. 622-6,
623-6 and No. 632H should be used. NFPA Standard No. 74 requires
the use of at least one smoke or combustion detector in every
residential installation.
Emergency Input: Connect open circuit momentary emergency switches (e.g.:
Nos. 219 and 4023) in parallel across these terminals. If none.are used, leave
these terminals empty.
Momentary operation of one of these switches at any time (system armed or dis-
armed) will cause the panic Supplemental Output Trigger to be produced. The inte-
gral speaker in the No. 4021 and the external siren speaker(s) will sound a loud
warbling tone. if the audible option has been selected (see "Option Selection" later
in this section).
In order to obtain the ability to activate a panic alarm from a remote No. 5240 com-
mand station (' and # pressed simultaneously), the VIOLET lead from the No.
5240 must be connected to terminal 10.
Digital Keypad Stations: Connect No. 5240 Digital Keypad Station(s) as required
and as indicated in Diagram 6. It should be noted that the Interior Zone Bypass
capability requires that a wire be run from terminal 11 to the "0" code pin of the 10
pin programming connector on each No. 5240.
System Arming Status Supplemental OutputS: Terminal 16 will output OV while
the system is disarmed (OFF) and + 6V while the system is armed (ON). Altema-
tively, terminal 17 provides OV while the system is armed (ON) and + 6V while dis-
armed (OFF).
